On 13 January 1941, the U.S. Army established the 78th Tank Battalion, the first black armored unit. On March 1941 The tankers reported to Fort Knox, Kentucky, to begin armored warfare training. On 8 May 1941 at Fort Knox, Kentucky the 78th Tank Battalion was re-designated as the 758th Tank Battalion (Light). It was the first of three units that would form the all-black 5th Tank Group. The 758th trained in mechanized warfare using the M5 light tank. One of the battalion's more notable members was future baseball star Jackie Robinson. Robinson was transferred to the unit from the 761st Tank Battalion after an incident in which he refused to move to the back of a civilian bus. The 758th was permanently attached to the 92nd Infantry Division until 22 September 1945 when the unit was deactivated. The unit's insignia is the head of a black African elephant with large white tusks accompanied by the motto, "We Pierce".
